Three Dollar Quill

Things that have happened with MOTR:

• The Mypy 1.7 update broke things; fortunately somebody else already filed a bug.
• I'm deep into the rewrite; it'll be interesting to see how badly the tests go, once the code looks reasonable.
• I ran into an absolutely inexplicable Mypy bug that I'll try to get a reproducer for once everything else is cleaned up.

Fortunately, I'm doing most of this on a branch. I had a sense that the update could be hairy, and it has been so, so much worse than I was anticipating.

Anyway, it's late and I'm tired. We'll see how this ends up tomorrow.

Good night.
